Two Zi Wei Dou Shu charts can share a basic main-star board while assigning different life questions to those stars. Mark the Life Palace, Body Palace, supporting stars, and transformations on both charts. Compare the common layout first, then the different starting points. A star pattern alone does not describe the same career or family situation.
Before comparing lives, mark each person's Life Palace and transformations. Identical main-star placement alone cannot answer two different career or family questions.
